Dr Marie-Paule Kieny (left), WHO Assistant Director-General, Health Systems and Innovation, and Professor Jorge Kalil, Director of the Butantan Institute of Sao Paulo take their seats for news conference2. SOUNDBITE (English) Dr Marie-Paule Kieny, WHO Assistant Director-General, Health Systems and Innovation:\"Vaccine development is still at an early stage, and the most advanced candidates are still a few months away from entering early human clinical trials. It is therefore possible that vaccines may come late for the current Latin American outbreak, but the development of a vaccine remains an imperative, and in particular vaccines suitable for pregnant women and women of child bearing age\"3. News conference 4. SOUNDBITE (English)  Professor Jorge Kalil, Director of the Butantan Institute of Sao Paulo:\"We think that in less than one year we can be in clinical (trials), and then if the regulatory people are following what they are doing and are very quick in their responses and the approval authority doing, then perhaps, in three years time we will have a vaccine. It will be very difficult to have a vaccine before that, in my opinion.\"5. Reporters6. SOUNDBITE (English) Dr Marie-Paule Kieny, WHO Assistant Director-General, Health Systems and Innovation:\"On vector control, we heard from experts at the consultation, that evidence is actually missing that classical vector control intervention has had any significant impact on transmission of Dengue, which is a virus which is close to the Zika virus. This is important, because we must be sure that we invest in interventions that work.\"7. Reporters8. SOUNDBITE (English) Dr Marie-Paule Kieny, WHO Assistant Director-General, Health Systems and Innovation:\"So, key knowledge gaps were identified, including the need to better understand the mosquito dynamic and the role of various species in virus dissemination. You know, there are plenty of species of mosquitoes, and we don't know which ones can transmit or not, apart from the major one identified, of course.\"9.
